Abstract
Silica (SiO2) nanolayer was coated on silicon carbide (SiC) powder by rotary chemical vapor deposition (RCVD). The SiC/SiO2 composite were consolidated by spark plasma sintering (SPS) at 1923 K using the SiO2 coated SiC powder. The relative density and hardness of the SiC/SiO2 composites increased with increasing SiO2 content, and were 97% and 17 GPa, respectively, at SiO2 content of 22 mass%. The relative density and hardness of a composite consolidated using the mixture powders of SiC and SiO2 (22 mass%) at 1923 K were 81% and 8 GPa, respectively.
